COIN-PROPELLING DEVICE Application filed June 5,

This invention relates to coin-propelling devices for coin-controlledvending ma lune-.1.

The object of the invention is to provide a device which will receive acoin of predetermined size, weight and composition, and

no other, and propel it across a gap.

A further object ofthe invention is to provide means for discharging anycoin of'a size smaller than that desired, so that it does not enter thecoin-controlled mechanism,

The invention consists of the construction, combination and arrangementof parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part hereof, is illustrated a formof embodiment of the invention, in which drawings similar referencecharacters designate corresponding parts, and in which:

Figure 1 is a vertical section through a casing, showing the applicationof the invention in side elevation;'-

Figure 2 is a vertical section through a casing, showing the applicationof the invention in rear elevation; 1 I

Fi ure 3 is a vertical section, taken from the front to the rear of thedevice, and centrally thereof, the coin to be used being shown in itsposition as it is about to enter the device; and

Figure 4 is a fragmentary detail in vertical section, similar to theleft hand end of Flg ure 3, the coin being shown in its second posltion,about to be propelled across the gap be tween the point of insertion andthe chute.

Referring to the drawings, 1 designates a casing having the usual slotor opening 2 n one wall thereof.

Disposed over theopening 2 is the usual form of plate 3 having a coinslot 4 therein, adapted to admit the passage of a coin 5.

Dis osed so as to register with the slot 4 there IS arranged a pair ofvertical plates 6, which may be secured to the plate 3 or to the wall ofthe casing 1. These plates for additional ri idity and for spacing aresecured together a jacent one corner by meansfof a rivet 6. The plates 6are arranged so that the space between'the same registers with the slot4.

The plates 6 are secured together by means of an upper rod 7 which isfixed with relation to the plates and disposed "on the rod 7 is afriction reducing member 8, preferably simply a washer disposed on therod 7 be- 55 tween the plates 6.

The plates 6 are further secured together son VENDING MACHINES.

by means of a lower rod 9 fixed with relation to the plates and arrangedto carry a friction reducing member 10 similar tothe washer 8.

A U-shaped member .11 is provided with upturned ends 12 and arrangedbeneath the loweredges of the plates 6 and maintained in one positon andb means of springs 13, secured at their lower ends to the upturned ends12 and secured at their upper ends-to any convenient adjacent part.

The lower edges of the plates 6 are slotted to receive the ends oftransverse rods 14 which are carried by the upturned ends 12 oftheiU-shaped member 11 and suitable friction reducing members 15 aredisposed on the rods14 between the plates 6. Normally the rod 9 and therods 14 occupy thesame vertical plane. However, when the coin 5 isinserted and falls downward by the pressure of the upper rod 7, the rods14 are forced downward, against the tension of the spring 13, to theposition shown in Figure 4.

' A partition or wall 16 is secured to the plate 3 and extendsrearwardly of the casmg 1. A magnet 17 is carried by the partition 16 sothat if a slug or imitation coin of base metal is inserted, it will beattracted by the magnet and withdrawn from its ordiiary path ofmovement.

A chute 18 is carried by the rear end of the partition 16 and its upperend is arranged in vertical alinement with the slot 4 and the openingbetween the plates ,6, and

its upper end is also arranged higher than the slot 4 so that the coin 5will pursue an arcuate path when inserted and operated upon by thefriction reducing members 8, 10 and 15. The tension of the springs 13 1sproportioned to the weight of the coin ofpredetermined size to be usedin the dev ce.

Secured to or carriedby the chute 18 is a downwardly projectin groovedway 19, the lower end 20of w ich is ofiset and curved away from thevertical plane-of the slot 4 ahd chute 18. This permits a coin Thetension of the spring 13 is thereby,

to the second position shown in Figure 3.

If the coin is of the diameter redetermined, it follows down the grooveway 19 into the coin box 21. If the coin is of the proper size but is ofbase metal, afiected by magnetism, the magnet 17 attracts it out of itsproper path so that it either sticks to the side of the wall, or isdeflected so thatit does not enter the chute 18. If the coin is of lessdiameter than the Width of the way 19 it drops through and does notfollow the tortuous passage of the Way and therefore does not enter thebox 21.

Having thus fully described the invention, what is claimed as new anddesired to be secured by Letters Patent is:

1. A coin-controlled device comprising a slotted plate, disposedadjacent thereto and registering therewith, an upper fixed frictionreducing member carried between the plates, a lower fixed frictionreducing member carried between the plates, a pair ofmovable frictionapair of vertical members.

reducing members carried between the plates intermediate of the slottedplate and the lower fixed friction-reducing member and a chute disposedin alinement with and at a point removed from the slotted plate.

2. A coin-operating device comprising a slotted plate, a pair ofvertical members disposed adjacent thereto, an upper fixedfriction-reducing member carried between the plates, a lower fixedfriction-reducing member carried between the plates, a pair of movablespring-retained friction-reducing members carried between the platesintermediate of the slotted plate and the lower fixed friction-reducingmember and a chute disposed in alinement with and at a pointremoved fromthe slotted plate.

3. A coin operating device comprising an insertion element, fixedfriction reducing means and resiliently supported friction reducin meansdisposed adjacent the insertion e ement and a chute in alinement withand at a point removed from the insertion element.
